聊天平台每天都会有大量的用户在线,会出现大量的聊天数据,通过对聊天数据的统计分析,可以更好的对用户构建精准的用户画像,为用户提供更好的服务以及实现高ROI的平台运营推广,给公司的发展决策提供精确的数据支撑。 我们将基于一个社交平台App的用户数据,完成相关指标的统计分析并结合BI工具对指标进行可视化展现。
基于Hadoop和Hive实现聊天数据统计分析,构建聊天数据分析报表
需求分析:
统计今日总消息量 统计今日每小时消息量、发送和接收用户数
统计今日各地区发送消息数据量
统计今日发送消息和接收消息的用户数
统计今日发送消息最多的Top10用户
统计今日接收消息最多的Top10用户
统计发送人的手机型号分布情况
统计发送人的设备操作系统分布情况
数据大小:30万条数据
列分隔符:Hive默认分隔符’\001’

问题1:当前数据中,有一些数据的字段为空,不是合法数据
问题2:需求中,需要统计每天、每个小时的消息量,但是数据中没有天和小时字段,只有整体时间字段,不好处理
问题3:需求中,需要对经度和维度构建地区的可视化地图,但是数据中GPS经纬度为一个字段,不好处理
